EDMUND R. COLLINS, OF NEW YORK, N. Y., ASSIGNOR TO NEW YORK DIE COMPANY,OF NEW YORK, N. Y., A CORPORATION OF NEW YORK.

EMBOSSING-PRESS.

To all whom it may concern:

Be it known that I, EDMUND R. COLLINS, a citizen of the United States,and a resident of the borough of Queens, city of New York, county ofQueens, and State of New York, have invented new and useful Improvementsin Embossing-Presses, of which the following is a specification.

This invention relates to means for adj usting the platen or moving partof presses, particularly that class of presses used for embossingpurposes and in which the platen or moving part is actuated by togglelevers arranged beneath and connecting it to the base of the frameprovided with vertical guide-ways in which it is fitted to slide.

The adjusting means of this invention is located between the lowerbearing of the toggle system and the base of the frame and is of acharacter to provide for the vertical adjustment of the platen or movingpart through a considerable range of motion, and

comprises a screw seated in a threaded hole formed vertically in orthrough the base of the frame and on or in which is seated the saidlower bearing of the toggle system, as will now be more particularlyreferred to by reference had to the accompanying draw ings, in whichFigure 1 represents a front elevation of a press provided with theimproved adjustment, and Fig. 2 is a vertical section taken on the line2, 2, Fig. 1.

The frame a may be of any suitable form and construction; it is providedwith vertical guide-ways 5, by which the platen c, by a flangedownwardly extending from it, or from a frame (Z on which the platenrests, is slidably held, and to the upper part of the frame is securedthe bed 6 which carries the die or embossing device The platen 0 iscontrolled by a toggle or kneejoint system of levers g, h, the upper endof the member 9 being pivotally connected to the platen carrier (Z andthe lower end of the member h pivotally held in a vertical plane withthe platen carrier connection of g. The central joint of the toggle isby a linkt Specification of Letters Patent.

connected to a crank j secured to one end of a shaft fitted in a bearing70 of the frame a, and to the other end of this shaft is secured ahandle Z, which when moved downwardly causes the toggle levers g and hto straighten and so presses any material placed on the platen 0 againstthe die f.

No claim is here made to any part of the press so far briefly described;the invention rests on the means for setting the platen in differentvertical positions, comprising a large flat headed screw on having acentral bore and fitting in a threaded hole vertically centrally formedin the base of the frame, a plate or disk a seated on the top of thehead of the screw on and provided with ears to which the lower ends ofthe lever h are pivoted and with a stem 0 fitting into the bore of thescrew m, a washer 7) held on the end of the stem 0 by any suitablemeans, as a screw 9, in such manner that while the screw m is free torotate around the stem there is no end-play between these parts so thelower pivotal bearing of the toggle system is fully controlled by thescrew m.

It is desirable in presses of the character here specified to provideconsiderable adjustment between the platen and the bed to accommodatedies and other devices, used in the presses, varying considerably indepth or thickness, and the screw adjustment here shown is particularlyadapted to meet such requirements by carrying and controlling the lowerjointed end of the platen actuating device, which may be a toggle leversystem, as here described, or other suitable means for moving the platentoward the bed of the press.

I claim A press of the character specified, comprising a verticallymoving platen, a frame having a base with a vertical screw-threadedhole, toggle-levers located between the platen and the base of thepress, a bearing for the lower joint of the toggle-levers, means foroperating the toggle-levers, and a screw fitted in the verticallythreaded hole in the base of the press having an upper head or flange onwhich is seated the lower bearing In testimony whereof, I have hereuntoof the toggle-lever, said screw having a censubscribed my name this 29thday of March, tral bore in which fits a stem downwardly 1910.

projecting from the lower bearing of the EDMUND R. COLLINS.togg1e-1evers, and a washer connected to the Witnesses:

stem and seated against the lower end of the J. C. MoKIBBIN,

screw. JAMES A. HUDSON.
